Ingredients  

  • 250 g fresh pumpkin, peeled deseeded and cut into chunks
  • 1 tsp neutral oil for roasting
  • 250 g brown sugar
  • 250 ml water
  • 1 stick cinnamon
  • 4 whole cloves
  • 3 allspice berries optional
  • 1 blade mace or a small pinch ground mace
  • ¼ tsp freshly grated nutmeg
  • ½ thumb-size piece fresh ginger, sliced or ½ tsp ground ginger
  • 1 pod vanilla
  • Pinch fine sea salt

Instructions 

  • Preheat the oven to 190°C. Toss the pumpkin chunks with the oil and spread in a single layer in a baking dish or on a lined tray. Roast for 25–30 minutes, turning once, until tender and lightly caramelised at the edges.
  • Transfer the roasted pumpkin to a bowl and blend with about 50 ml water until completely smooth. Measure out 125 g of pumpkin purée; reserve any extra for another use.
  • In a small dry pan over medium heat, toast the cinnamon stick, cloves, allspice berries and mace for 1–2 minutes, stirring occasionally, until fragrant. Remove from the heat and lightly crush the spices with a mortar and pestle or the back of a spoon.
  • Split the vanilla pod and scrape out the seeds. Add the pumpkin purée, brown sugar, 250 ml water, crushed spices, sliced ginger, grated nutmeg, vanilla seeds and pod, and a pinch of salt to a saucepan. Stir well to dissolve the sugar.
  • Bring to a gentle simmer over medium-low heat. Cook for 10–12 minutes, stirring occasionally, until slightly thickened and the syrup coats the back of a spoon. If it looks too thick, whisk in 1–2 tbsp hot water; if too thin, simmer for a few minutes longer.
  • Remove the vanilla pod. Pour the mixture through a fine mesh sieve or muslin cloth set over a bowl. Press lightly with a spoon to extract more liquid; a little sediment is fine for a more rustic finish. For a clearer syrup, allow it to drain without pressing.
  • Transfer the strained syrup to sterilised bottles or jars. Let cool completely, then seal and refrigerate for up to 3 weeks. Shake before use, as some natural separation may occur.

Notes

Variations and Substitutions

Maple version:
Swap 50–75 g of the brown sugar for maple syrup for a softer sweetness and a slight smoky edge. Reduce the water by a tablespoon or two to keep the texture consistent.
Spicier blend:
Add a small piece of star anise or increase the ginger for a sharper, more aromatic result. If you prefer a milder profile, cut the cloves in half.
Darker, richer syrup:
Use dark brown sugar or add a teaspoon of molasses for a deeper, more robust flavour. This works well in strong coffee where lighter syrups can get lost.
If you don’t have mace:
Use a small pinch of extra nutmeg. The flavour won’t be as floral, but it keeps the balance of the blend intact.
If you don’t have a vanilla pod:
A teaspoon of good-quality vanilla extract works fine. Add it off the heat to keep the flavour clean.
Storage:
The syrup keeps in the fridge for about three weeks in a sealed jar. It also freezes well — portion it into small containers or ice-cube trays and thaw in the fridge, then stir to bring the texture back together.
